Foil sarking is a commonly used product for wrapping Australian homes, in this video we cover the reason why we wrapped homes. The reason why foil sarking (radiant barrier) became a common product used in Australian construction, and why we need to transition away from these products, and more to higher quality products that are based on sound building physics principles.

* Reducing moisture content in wall cavities,

* reducing air flow in wall systems, and increasing insulation performance,

* while providing a services cavity that assists services to be installed without effecting building performance.

This video covers all these important concepts, for better performing wall systems in Southern Australia and Northern Australia.

Solar panel problems! Early detect with Thermal imaging.

The continuous growth of the solar industry brings an ever-expanding base of solar installations. While many solar panels are expected to provide a 20-year life span, this is often not the case with cheaper quality solar panels but even high-quality panel can fail prematurely. thermography technology can save time and make troubleshooting solar panel installations an easy and cost-effective service. Thermal imaging cameras look for panel hotspots. Overheated cells can damage the casing material and cause delamination. When modules overheat due to shading, defective cells, or substrings these overheating components consume energy instead of producing energy, the module efficiency can drop by around .5% per degree Celcius. Where do the hotspots come from? Shade on the module or a defective cell can change the module from power production to power consumption resulting in heating the cell which will show as a hotspot in a thermal image. A defective or mismatched bypass diode may cause the same effect.

Building wraps/membranes are useful for so many reasons. Building performance is only a part of the picture, when looking at control layers, with building envelope loads. When considering where the building is and what environment a building is maintaining, it becomes clear what we should be expecting from our wall systems.

Protecting the building during construction from weather conditions. over the duration of the build.
Controlling moisture in wall cavities is critical with a vapour barrier.
Improving insulation performance
Stopping moisture from outside getting into your wall system, and stopping moisture from inside getting in a wall system, with a vapour barrier on other circumstances.
